The Untethered Miniature Origami Robot, created by scientists at MIT is a 1.7cm square device powered by a neodymium magnet and four subsurface electromagnetic coils that allow the robot to assemble itself like an origami sculpture, walk, climb, carry objects twice its weight, swim in shallow water, burrow and dissolve in an acetone solution leaving nothing but the magnet behind.

This is a 15 minute sci-fi film set on an Irish farm in the near future where the robots are slowly but surely taking over. It was made by some of my students 2 years ago and has just been released ‘into the wild’. I think your audience would get a buzz out of it.
